Description: Prepares groundwater-level observations from measured
        hydraulic head or from depth-to-water and land-surface
        elevation, interpolates potentiometric surfaces using
        thin-plate splines, inverse-distance weighting, ordinary
        Kriging, universal Kriging, or user-supplied methods, and
        creates raster, contour, diagnostic, support, and
        hydraulic-gradient products for review and export. Functions
        retain method conditions and fit diagnostics, validate explicit
        prediction tasks, inspect model-conditional uncertainty and
        monitoring-network sensitivity, identify limited prediction
        support, and check whether scaled hydraulic-gradient arrows
        remain within finite raster support and end at lower modeled
        head. Raster processing uses methods from 'terra' (Hijmans
        2025) <doi:10.32614/CRAN.package.terra>, thin-plate splines use
        methods from 'fields' (Nychka et al. 2021)
        <doi:10.5065/D6W957CT>, and geostatistical interpolation uses
        methods from 'gstat' (Pebesma 2004)
        <doi:10.1016/j.cageo.2004.03.012>.
